And is imaged on the photoelectric conversion surface 2. This image formation is the same as that of the above-described conventional apparatus, and a detailed description thereof will be omitted. X-rays incident on the photoelectric conversion surface 2 are converted into electrons, and photoelectrons corresponding to the amount of incident light are emitted to the side opposite to the incident side. The emitted photoelectrons are accelerated by the acceleration electrode 5 in substantially the same direction as the X-ray incidence direction, and are enlarged and imaged on the input surface of the MCP 4 by the electromagnetic focusing coil 6 having the function of an electron lens. At the time of this image formation, the photoelectrons are supplied to the electromagnetic deflection coil 7.
As a result, as shown by the dotted line A in FIG. 1, the tube 1 is bent along the bend, and an enlarged image is formed on the input surface of the MCP 4 provided inside the other end of the tube 1.

きる。On the other hand, the X-rays transmitted through the photoelectric conversion surface 2 are not affected by the accelerating electrode 5, the electromagnetic focusing coil 6, and the electromagnetic deflecting coil 7, so that the X-rays travel straight as indicated by B in FIG. And does not directly reach the input surface of MCP4. For this reason, the X-rays that have transmitted through the photoelectric conversion surface 2 are
, And the background noise caused by this is suppressed. Therefore, only photoelectrons are incident on the input surface of the MCP4, and a clear enlarged image can be obtained.

よい。Further, since the restriction aperture ring 8 is provided, even if the X-rays transmitted through the photoelectric conversion surface 2 collide with the inner wall portion of the bent portion of the tube body 1 and are reflected in the direction of the input surface of the MCP 4, the X-rays are restricted. MCP4 shaded by aperture ring 8
Does not enter the input surface. This further enhances the effect of suppressing background noise. In addition, as a method of eliminating the influence of the reflection in the tubular body 1, various methods can be considered other than the method of providing the limiting aperture ring. For example, as shown in FIG. The straight pipe 9 may be connected to guide the transmitted X-rays therein.

置。2. An image tube apparatus comprising: photoelectric conversion means for converting incident light into electrons and outputting the electrons; and electron acceleration means for accelerating photoelectrons emitted from the photoelectric conversion means in substantially the same direction as the incident direction. A deflecting unit that bends the traveling direction of the photoelectrons accelerated by the unit and guides the outgoing region of the incident light transmitted through the photoelectric conversion unit; and Image output means for outputting an image from the photoelectrons guided by the means, and the reflected light due to the reflection of the incident light transmitted through the photoelectric conversion means reaching the image output means, by guiding the incident light into the inside. An image tube device with a straight tube to prevent.
